摘要
本文通过分析介形类化石组合与生态特征，结合优势度与信息函数分异度分析，进而探讨东营凹陷的古环境。认为东营凹陷沙三晚期存在以下５种环境：冲积－滨湖；冲积－三角洲平原；浅湖－三角洲前缘；较深湖－前三角洲和湖湾环境。
The paleoenviroment of Dongying Sag is studied by focusing on the features of Ostracoda fossil community and paleoecology, especially the dominance(dm) and diversity(Hs)of Ostracoda. The five enviroments in the late shahejie Ⅲ(Oligocene) of Dongying Sag are distinguished: 1) floodplain-coastal lake; 2 ) alluvial delta plain; 3) shallow lake-delta fron; 4)sub-deep lake-prodelda ;5)lake bay.
